This invention relates heat deflectors and IfIlOI'B particularly to a warm air filter there- The primary object of this invention re sides in the provision of means adapted to be associated with heat distributing units of building heating systems whereby warm air emitted from the heat distributing units will be purified prior to discharge into the rooms 10 of buildings. I I

Another objectof this invention resides in the provision of means adapted to be associated withheat distributing units of building heating systems so as to permit free circulation of the warm air emitted from the heat distributing units and separate foreign matter in the Warm air prior to discharging the warm air intothe rooms of the building.

' A still further object of this invention re- 2() sides in the provision of a heat deflector,

adapted to be associated with heat distributing units of building heating systems,so as to check the flow of foreign matter carried by the warm air emitted from the heat distributes. ing units and permit normal flow of pure air intothe rooms of the building.

In addition to the aforesaid, objects, this invention resides in the provision of a heat deflector with which is associated a warm air filter adapted to separate foreign matter from warm air and retain it for disposal when cleaning the filter.

.Aside from the foregoing objects, this invention resides in the provision of a particularly constructed warm air deflector having 1 a filter associated therewith, which not only functions in the capacity of purifying air passing theret-hrough, but is so arranged that it will function as a damper when manipu- 40 lated qut of normal position.

Among the objects heretofore set forth,

this invention resides in the provision of a warm air deflector consisting of an association of elements which are readily assembled 46 to present an ornamental adjunct to the heat distributing units of building heating sys-. tems.

' Included among the several objects of this invention an association of elements is intro-' duced whereby the purification of ,warm air 50 emitted from the heat distributing units 0 buildlng heating systems, is accomplished by directing it through or against a fibrous filter capable of retaining or collecting foreign matter carried by the air passing therethrough.

With these and other objects in view this invention resides in certain novel features'of construction, arrangement and combination of elements to be hereinafter-more fully set forth in the specification, illustrated in the.

drawings and pointed out in the appended claims and, while the disclosure depicts my present conception of the-invention, the right is reserved to make such changes in construction as come-within the scope of the claims.

In the accompanying drawings forming a part of this application Fig. 1 is a perspective View of a deflector constructed in accordance "with this inven- 7 tion, showing the same associated with aregister of a hot-air heating system Fig.2 is an enlarged verticalsectional view thereof, approximately online 2 2 of Fig. 1;

Fig. 7 is a vertical sectional view thereof,

approximately on line 7'-7, showing thefilter in normal position by full lines and in dotted lines as utilized in functioning as a damper;

Fig, 8 is a vertical sectional view of a tieflector utilizing a plain fibrous or similar sheet of material as a filter'.

In the present embodiment of this invention, the numeral 5 designates a hot air de- 5 flector of suitable design adapted to be "associated with the heat distributing units of building heating systems and preferably consists of side members 6 having opposed channels 7 along their edges 8 for the reception of the edges 9 of a deflecting wall 10.

The aforesaid deflecting wall 10 has its for-. ward and rear ends 11 and 12 rolled for the accommodation of rods 13 or the like,'which are utilized to secure the side members 6 and 15 deflecting wall-10 in rigid relation and prevent-slippage of the deflecting wall in the channels 7. p

Appropriately arranged in the rolled end 11 of the deflecting wall is a series of a erzo-tures 14 adapted to emit air directed against the deflecting wall. Suitably secured in spaced relation beneat the deflecting wall 10 of the deflector is a filter I 25, which consists of-an apertured back plate 26, in opposed relation to the inner surface of the deflector wall, to provide an. air passage 1 immediately above the filter for conducting airtoward and through the apertures 14: in

the rolled end of the deflector wall 10. Suitablyattached to the back plate 26 on that surface opposite to the air passage, thus formed, are a plurality of laterally extending bafiies v 27, which are formed from reticulated or other suitable material adapted to carry or support laterally extending catch basins 28 along their lowermost areas or therebeneath, so as to catch soot or other foreign matter collected or separated by a filtering material 29 confined between the walls of the baflies and above the catch basins.

Although the bafiles 27 may be formed in any desired shape for association'with a filtering material and the catch basins, the same are herein constructed in compound ogee configuration so as to provide pockets 30 for retainin the filtering material and catch basins. To acilitate removal of the filter from the deflector, for cleaning, a bolt 31 or other suitable element ispassed laterally through the.

same and side members 6 and retained against displacement by a thumb-nut 32. p

With the aforesaid elements assembled, a hotair filtering deflector is provided for association with the heat distributing units of I 55 buildin heating systems, so as to direct the air, emitted or otherwise discharged there-.

freely therethrough.

ters Patent is:

open area covered with a reticulated material 32" or other ornamental screen and is adapted to hingedly support a filter 33, so as to be manipulated in close roximity to the deflecting wall thereof, to unction as an air puri- 7o fier, and lodged over the-open area of the deflector, inward of the cover thereof, to function as a damper. a v

The deflector shown in Fig. 8 is of any suitable design and has a filter 36 likewise asso- 7 ciated with its deflecting wall, and in this instance it is of a fireproof fibrous character supported beneath the deflecting wall, so as to collect foreign matter and permit air to flow Since deflectors of this character are especially designed to be associated with hot-air heating systems, their application as adjuncts to other heating systems is apparent and, while the type herein illustrated is of a stationary floor design, certain conditions necessitate minor alteration thereof to utilize the same on walls, in addition to pivotally secur-.

ing them to their supports, and therefore the right is reserved to. construct them to meet de- -mands in their successful operation.

With this invention fully set forth, it is ap: parent that a deflector is introduced which will readily function to purify warm air passing therethrough and, through the particular association of elements, the cost. of manufacture will be reasonable.

What I claim'and desire to protect by Letg '1. Anair deflector of the character set 1 forth, the combination of reticulated hollow baflles disposed in spaced vrelation'to'the deflecting surface of the deflector and extending. outwardly therefrom, filtering material asso-' j ciated with the baflles, and catch basins posi tioned at the lower edges of the bafiies.

2.. An air deflector of the character set forth, having its deflecting wall. provided with a series of apertures at its front end, a borru ated'forammous bafiie havin' its corrugatlons extending laterally beneat the deflecting Wall of the deflector, a vcatch basin at the lowest part of each corrugation, and an air outlet iassage between the bafile and deflecting wa l of the;.deflector. I i

. 3.v An air deflector of the character set forth, the combination of av plurality of laterally extending baflles formedof reticulated materlal, an apertured back plate supporting the baflles and disposed in spaced relation to the deflecting wall of the deflector, catch basins'supported on the lowermost walls of the bafiies, filtering material housedby the baflles, and an air exit passage between the backplate and deflecting wall of the deflector.

4. n' an air'deflector of the character set forth, the combination "of-a corrugated foraminous baflie plate associated with the deflectin wall of the deflector, filtering mate.- rial disposed in the corrugations of the foraminous bafiie plate and catch basins sup ported by the foraminous baffle plate at the lowermost portions of the corrugations thereof.

5. The combination of an air deflector hav- 7 ing an .open front portion covered with a screen, and an air'filter pivoted within the deflector to swing over and away from said opening.

In testimony whereof I afiix my signature. EDWARD .W. LITTLE.'
